However, in actual operations, the surface of the segments is often covered with impurities such as mud, dust, and concrete residue. If these impurities are not removed in a timely and effective manner, it may lead to suction cup seal failure, segment positioning deviation, or even the risk of segment detachment.

[0003] With the in-depth exploration of automation technology, relevant researchers have proposed integrating three independent mechanisms—air washing, water washing, and sweeping—on the tunnel boring machine to achieve dust removal during the segment hoisting and transportation process.

[0058] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0059] In the embodiments of this application, the terms "first" and "second" are used to distinguish identical or similar items with substantially the same function and effect. Those skilled in the art will understand that the terms "first" and "second" do not limit the quantity or execution order, nor do they necessarily imply difference. It should be noted that in the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design scheme described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or design schemes. Specifically, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner. In the embodiments of this application, "at least one" refers to one or more, and "more than one" refers to two or more.

[0060] It should be noted that the phrase "at...time" in the embodiments of this application can refer to the instant at which a certain situation occurs, or to a period of time after the occurrence of a certain situation; the embodiments of this application do not specifically limit this. Furthermore, the pipe segment cleaning method provided in the embodiments of this application is merely an example, and pipe segment cleaning methods may include more or fewer elements.

[0061] In the field of shield tunnel construction, tunnel segments are key components of tunnel lining, and their surface cleanliness directly affects the adsorption effect of vacuum suction cups on the segments and the subsequent construction quality. However, in actual operations, the surface of the segments is often covered with impurities such as mud, dust, and concrete residue. If these impurities are not removed in a timely and effective manner, it may lead to suction cup seal failure, segment positioning deviation, or even the risk of segment detachment.

[0062] In the industry, traditional methods generally use manual hand tools (such as wire brushes and high-pressure water guns) for local cleaning. This method is not only time-consuming, labor-intensive, and inefficient, but also makes it difficult to ensure uniform cleaning. Especially in complex working conditions, operators need to stand on the edge of the trolley or on the track of the battery vehicle to clean the rapidly rotating suction cups or sharp edges at close range, which poses significant safety hazards.

[0063] With the deepening exploration of automation technology, researchers have proposed integrating three independent mechanisms—air washing, water washing, and sweeping—on tunnel boring machines to achieve dust removal during segment hoisting and transportation. While this solution reduces manual intervention to some extent, its multi-mechanism integration design results in a complex equipment structure, with intertwined air, water, and mechanical transmission systems, making operation and maintenance difficult. The complex multi-system linkage control logic means that a failure in any link can cause the entire production line to shut down. Furthermore, the continuous consumption of compressed air and water resources does not align with green construction principles, and the high cost limits its widespread adoption. These technical bottlenecks have prevented this solution from becoming mainstream in the industry.

[0064] Therefore, existing technologies have several key shortcomings:

[0065] On the one hand, existing technologies require the addition of complex equipment such as high-pressure air circuits, water circuits, or robotic arms, resulting in high hardware investment, structural redundancy, and increased maintenance difficulty and cost.

[0066] On the one hand, manual cleaning requires workers to operate at close range in a high-risk environment, which poses risks such as suction cup rotation collisions and scratches from sharp edges of the tubes; on the other hand, the coordinated control of rotating parts and robotic arms in automated solutions may also cause safety issues.

[0067] On the one hand, manual cleaning relies on experience, is inefficient and results in uneven cleaning; on the other hand, existing automated solutions mostly use a single airflow or water washing mode, which is difficult to cover complex contaminated areas on the pipe surface, thus limiting the cleaning effect.

[0068] On the one hand, multi-mechanism integrated solutions continuously consume compressed air and water resources, which is inconsistent with the green construction orientation, and the high energy consumption mode limits its application in large-scale projects.

[0069] On the other hand, existing cleaning systems are highly dependent on air source pressure. When the air source for the tunnel boring machine is interrupted, the cleaning process is easily interrupted, affecting the continuity of construction.

[0070] To address the aforementioned issues, the inventors, during their research on the low cleaning efficiency of tunnel segments, discovered that existing technologies rely on manual tools or automated systems integrating multiple mechanisms for segment cleaning. This results in high equipment complexity, high maintenance costs, and safety risks for personnel. Furthermore, traditional automated solutions require additional air washing, water washing, and sweeping mechanisms, leading to complex control logic due to the intertwining of air, water, and mechanical transmission systems, and continuous consumption of compressed air and water resources, which does not meet the requirements of green construction. Under complex working conditions, workers must operate at close range in a high-risk environment, posing safety hazards such as suction cup rotation collisions and scratches from sharp edges of the segments. Therefore, the inventors considered reusing the existing air source and segment system of the vacuum suction cup, combined with an automatic switching mechanism controlled by sensors and relays, to achieve automatic cleaning of the segments before suction without adding new specialized equipment, while ensuring cleaning uniformity, system stability, and construction safety. Based on this, embodiments of this application provide a segment cleaning system, method, apparatus, equipment, medium, and product, applicable to the tunnel construction field, aiming to solve the problem of low cleaning efficiency of existing tunnel segments.

[0071] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0072] Figure 1 This is a schematic diagram of the system architecture for a pipe segment cleaning system provided in an embodiment of this application. The pipe segment cleaning system comprises electronic and mechanical equipment. Figure 1 In the process, the segment cleaning system 10 includes a detection structure 11, a control structure 12, and a cleaning structure 13.

[0073] It is understood that the structures illustrated in the embodiments of this application do not constitute a specific limitation on the architecture of the cleaning system for pipe segments. In other feasible embodiments of this application, the above architecture may include more or fewer components than illustrated, or combine some components, or divide some components, or arrange different components, which can be determined according to the actual application scenario and is not limited here.

[0074] Optional, Figure 2 This is a schematic diagram of a segment cleaning system provided in an embodiment of this application, as shown below. Figure 2 As shown:

[0075] It should be noted that the segments include ordinary segments and non-ordinary segments. The size and cleaning range of ordinary and non-ordinary segments are different.

[0076] Specifically, based on the specifications of the segments being absorbed, they are divided into ordinary segments and non-ordinary segments. Non-ordinary segments are smaller than ordinary segments.

[0077] Among them, non-ordinary segments can be K-type segments.

[0078] It should also be noted that the tunnel segments were transported by crane. During the transport of the tunnel segments, the vacuum pump 206 remained operational.

[0079] The detection structure 11 includes a pressure switch 201 and a ranging structure.

[0080] Specifically, pressure switch 201 is used to detect the pressure status of the air source 202 of the tunnel boring machine and obtain a pressure signal.

[0081] Optionally, the ranging structure includes a standard block ranging sensor 203 and a non-standard block ranging sensor 204.

[0082] Specifically, the ranging structure is used to detect the distance between the tube segment and the suction cup 205 to obtain the ranging result.

[0083] The control structure 12 is connected to the detection structure 11.

[0084] The control structure 12 includes a gas source structure and a gas source selection structure, which are connected by pipelines.

[0085] Optionally, the air source structure includes a vacuum pump 206 and a tunnel boring machine air source 202.

[0086] Specifically, the gas source structure is used to generate gas.

[0087] Specifically, the gas source selection structure is used to switch the current gas source to the vacuum pump 206 or the tunnel boring machine gas source 202 based on the pressure signal.

[0088] For example, when the pressure switch 201 determines that the air supply 202 of the tunnel boring machine is interrupted due to a fault based on the detected pressure signal, the pressure switch 201 switches the air supply source from the air supply 202 of the tunnel boring machine to the vacuum pump 206, thereby ensuring the continuity of the cleaning process.

[0089] Optionally, the gas source selection structure includes a vacuum pump gas source switching valve 207 and a clean gas source selection valve 208.

[0090] More specifically, the clean air source selection valve 208 is used to switch the current air source to the vacuum pump 206 or the tunnel boring machine air source 202 based on the pressure signal.

[0091] The control structure 12 also includes a negative pressure vacuum chamber 216.

[0092] For example, when vacuum pump 206 is selected as the gas supply source, vacuum pump gas source switching valve 207 switches from negative pressure vacuum chamber 216 to atmospheric air for pumping, and the gas is discharged from the exhaust port of vacuum pump 206 through clean gas source selection valve 208.

[0093] More specifically, the vacuum pump gas source switching valve 207 is used to switch the current working mode to vacuum adsorption mode or cleaning mode based on the ranging result.

[0094] The cleaning structure 13 includes a cleaning solenoid valve structure, an adsorption solenoid valve structure, and a suction cup structure.

[0095] Optionally, the cleaning solenoid valve structure includes a standard block cleaning solenoid valve 209 and a non-standard block cleaning solenoid valve 210.

[0096] Optionally, the adsorption solenoid valve structure includes a standard block adsorption solenoid valve 211 and a non-standard block adsorption solenoid valve 212.

[0097] Optionally, the suction cup structure includes suction cup 205 and vacuum suction port structure.

[0098] The vacuum suction port structure is located on the adsorption surface of the suction cup 205, and the vacuum suction port structure is the exhaust port of the suction cup 205.

[0099] The cleaning structure 13 is connected to the control structure 12 and the detection structure 11 respectively.

[0100] Specifically, the cleaning structure 13 is used to determine whether to enter cleaning mode based on the ranging results.

[0101] Specifically, in cleaning mode, the cleaning gas source blows the cleaning gas from the suction cup structure onto the surface of the tube segment for cleaning through the gas source selection structure, the cleaning solenoid valve structure, and the adsorption solenoid valve structure.

[0102] More specifically, cleaning gas is blown out from the vacuum suction structure to clean the surface of the tube sheet.

[0103] Optionally, the vacuum suction port structure includes a right cavity vacuum suction port 213, a non-ordinary block cavity vacuum suction port 214, and a left cavity vacuum suction port 215.

[0104] For example, when the distance measured by the ordinary block ranging sensor 203 and the non-ordinary block ranging sensor 204 enters the cleaning working range, it is determined whether to select only the non-ordinary block cleaning solenoid valve 210 to work, or to select both the ordinary block cleaning solenoid valve 209 and the non-ordinary block cleaning solenoid valve 210 to work simultaneously.

[0105] Furthermore, the clean air source discharged from the previous step's clean air source selection valve 208 is introduced into the exhaust ports (vacuum suction port 213 of the right cavity of the tube segment, vacuum suction port 214 of the non-ordinary block cavity of the tube segment, and vacuum suction port 215 of the left cavity of the tube segment) of the suction cup 205 for dust removal and cleaning of the tube segment surface (tube segment suction surface).

[0106] It should be noted that the vacuum pump gas source switching valve 207 is a two-position three-way solenoid valve used to control the intake port of the vacuum pump 206, switching the intake gas source from the negative pressure vacuum chamber 216 to be open to the atmosphere. The intake air is discharged through the exhaust port of the vacuum pump 206 and then discharged through a two-position four-way gas source selection valve, serving as one of the main gas sources for segment cleaning.

[0107] Furthermore, the shield machine air source 202 with pressure detection is connected to another interface of the aforementioned two-position four-way air source selection valve, and the shield machine air source 202 is used as the second air source for segment cleaning.

[0108] Furthermore, based on the pressure detection signal of the tunnel boring machine's air source 202, the two air sources are automatically switched. Clean air from the two-position four-way air source selection valve is introduced into the ordinary block cleaning solenoid valve 211 and the non-ordinary block cleaning solenoid valve 212 through the ordinary block adsorption solenoid valve 209 and the non-ordinary block adsorption solenoid valve 210, and finally introduced into the adsorption surface of the segment for cleaning and dust removal through the original pipeline and suction port (vacuum suction port 213 for the right cavity of the segment, vacuum suction port 214 for the non-ordinary block cavity of the segment, and vacuum suction port 215 for the left cavity of the segment) of the suction cup 205.

[0109] Furthermore, the ordinary block distance sensor 203 and the non-ordinary block distance sensor 204, mounted on the side of the suction cup 205, automatically open and close the ordinary block cleaning solenoid valve 209 and the non-ordinary block cleaning solenoid valve 210 according to the size of the tube and the set distance, completing the automatic cleaning and dust removal operation. The cleaning process is automatically adjusted based on the distance sensor data to ensure uniformity and thoroughness, avoiding over-cleaning or under-cleaning, and improving cleaning efficiency. At the same time, the improved cleaning efficiency also extends the lifespan of the sealing strip.

[0110] It should be noted that the pressure switch monitors the pressure of the tunnel boring machine's own air source in real time. When the air source pressure is insufficient, the air source selection valve switches to the vacuum pump exhaust port path to ensure a stable supply of clean air.

[0111] It should be noted that the cleaning process is carried out during a short window before the suction cup is engaged. The cleaning gas is discharged through the air intake at the bottom of the suction cup, requiring no extra time. At the same time, the original structure of the suction cup is used to achieve uniform cleaning.

[0112] It should be noted that by using the existing air source and tube system of the vacuum suction cup, there is no need to add complex equipment such as high-pressure air circuits, water circuits, or robotic arms, significantly reducing hardware investment and saving costs. This embodiment features fully automated cleaning, avoiding personnel standing on the edge of the trolley and close contact with the rotating suction cup or sharp tube edges, eliminating safety hazards. Furthermore, the tube cleaning process is deeply integrated with the vacuum suction cup adsorption process, automatically completing the cleaning during the brief window before suction cup adsorption, requiring no additional labor.

[0113] This application provides a tube segment cleaning system, comprising: a detection structure including a pressure switch and a ranging structure; a control structure connected to the detection structure, the control structure including an air source structure and an air source selection structure, the air source structure and the air source selection structure being connected via pipelines; and a cleaning structure including a cleaning solenoid valve structure, an adsorption solenoid valve structure, and a suction cup structure, the cleaning structure being connected to both the control structure and the detection structure. Compared to existing technologies, automated equipment is often cumbersome, difficult to maintain, and prone to failure, resulting in low tube segment cleaning efficiency. This application, by reusing the existing air source and tube segment system of the vacuum suction cup, combined with an automatic switching mechanism controlled by sensors and relays, achieves a deep integration of tube segment surface cleaning and vacuum adsorption processes, thereby improving the tube segment cleaning efficiency.

[0114] The technical solution of this application will be described in detail below with reference to specific embodiments:

[0115] Figure 3 A schematic flowchart of a segment cleaning method provided in this application embodiment. Figure 1 ,like Figure 3 As shown, the cleaning method for tunnel segments is applied to... Figure 1 and Figure 2 The segment cleaning system, used for cleaning the tunnel segments, includes the following methods:

[0116] It should be noted that, as Figure 2 As shown, B3 is a pressure switch 201, B2 is a common block ranging sensor 203, B1 is a non-common block ranging sensor 204, V5 is a vacuum pump gas source switching valve 207, V6 is a clean gas source selection valve 208, V4 is a common block cleaning solenoid valve 209, V3 is a non-common block cleaning solenoid valve 210, V1 is a common block adsorption solenoid valve 211, V2 is a non-common block adsorption solenoid valve 212, the right cavity vacuum suction port 213 of the tube segment is responsible for Part I, the non-common block cavity vacuum suction port 214 of the tube segment is responsible for Part II, and the left cavity vacuum suction port 215 of the tube segment is responsible for Part III.

[0117] It should also be noted that the working phases of the tube segment cleaning system include a cleaning phase and a non-cleaning phase. This example is in the cleaning phase. In the non-cleaning phase, V5 is not working, and the BC ports of V5 are connected. The vacuum pump continuously extracts air from the vacuum chamber of the suction cup to create negative pressure, preparing for the suction of the tube segment. At the same time, V1, V2, V3, V4, and V6 are all not working.

[0118] S301. Obtain the segment information.

[0119] The segment information includes segment attributes.

[0120] S302. Determine whether the segment is a regular segment or a non-regular segment based on the segment attributes.

[0121] S303. When the tunnel segment is a regular tunnel segment, obtain the distance measurement of the regular segment and the distance measurement of the non-regular segment.

[0122] In this embodiment, when B3 detects that the air source of the tunnel boring machine has no pressure and sucks up ordinary tunnel segments, V6 does not move according to the control circuit principle, the crane moves to directly above the tunnel segment and begins to descend vertically, and B1 and B2 start to work.

[0123] In one possible embodiment, Figure 4 This is a schematic diagram of the clean gas source switching process provided in the embodiments of this application, such as... Figure 4 As shown, when B3 detects no pressure in the tunnel boring machine's air source, V5 is energized, and V6 is energized but does not operate according to the control circuit principle; the vacuum pump then replaces the tunnel boring machine's air source. When B3 detects pressure in the tunnel boring machine's air source, V5 is de-energized and does not work according to the design, and the BC port is directly connected to the negative pressure vacuum chamber; according to the circuit design, V6 is de-energized, and the vacuum pump exhausts air directly into the atmosphere through the AD port of V6; the tunnel boring machine's air source replaces the vacuum pump's exhaust air source and introduces it into the cleaning system through the BC port of V6.

[0124] S304. Based on the distance measurement of ordinary blocks, the distance measurement of non-ordinary blocks, and the preset first distance measurement adjustment strategy, confirm whether to enter the vacuum adsorption mode or the cleaning mode.

[0125] S305. When entering the cleaning mode, the surface of the tube segment is cleaned according to the preset cleaning strategy.

[0126] Specifically, Figure 5 This is a schematic diagram of the automatic cleaning process for tunnel segments provided in an embodiment of this application. Figure 6 This is a schematic diagram of the control circuit structure for automatic cleaning of tunnel segments provided in an embodiment of this application, as shown below. Figure 5 , Figure 6 As shown:

[0127] Optionally, when the distance between B1 and B2 is greater than 600mm, the vacuum adsorption mode is entered: V5 does not operate according to the design, the BC port of V5 is connected, the negative pressure chamber is continuously evacuated, and V1, V2, V3, and V4 are de-energized and do not operate according to the design.

[0128] Optionally, when the distance between B1 and B2 is less than or equal to 600mm, the cleaning mode is entered: V5 is energized and engaged as designed, the AB port of V5 is connected, the C port is closed, and the A port is connected to the atmosphere. Air is drawn into the vacuum pump through the AB port to provide an air source for cleaning and dust removal.

[0129] At this time, according to the circuit principle design, V3, V4, and V5 are energized and activated synchronously, while V1 and V2 are de-energized and do not activate. The air drawn in is then discharged through the vacuum pump exhaust port, through the AB port of V6 when it is de-energized, through the A and B ports of V3 and V4, through the BC ports of V1 and V2, and finally through the suction ports at the bottom of the suction cup (vacuum suction port for the right cavity of the tube, vacuum suction port for the non-ordinary block cavity of the tube, and vacuum suction port for the left cavity of the tube), thus achieving automatic cleaning of the tube surface.

[0130] Optionally, when the suction cup continues to descend and the distance feedback value between B1 and B2 is less than 100mm, V3, V4, and V5 will be de-energized and reset according to the design principle. The BC port of V5 will be connected, the vacuum pump will be connected to the negative pressure chamber, and the vacuum will continue to be pumped. The exhaust gas from the vacuum pump will be discharged to the atmosphere through the AD port of V3 and V4.

[0131] This embodiment provides a method for cleaning pipe segments. The method is applied to a pipe segment cleaning system used to clean pipe segments. The method includes: acquiring pipe segment information; determining whether the pipe segment is a common or non-common pipe segment based on its attributes; when the pipe segment is a common pipe segment, acquiring the common block distance and the non-common block distance; determining whether to enter a vacuum adsorption mode or a cleaning mode based on the common block distance, the non-common block distance, and a preset first distance adjustment strategy; when entering the cleaning mode, cleaning the pipe segment surface according to a preset cleaning strategy. Compared to existing technologies, automated equipment has a complex structure, is difficult to maintain, and is prone to failure, resulting in low cleaning efficiency for pipe segments. This application implements a simple, efficient, and reliable controllerless automatic cleaning control system based on sensors and relays. Automatic switching through air source pressure detection ensures the stability and continuity of the cleaning process, thereby improving the cleaning efficiency of the pipe segments.

[0132] Figure 7 A schematic flowchart of a segment cleaning method provided in this application embodiment. Figure 2 ,like Figure 7 As shown, step S302 further includes:

[0133] S701. When the tunnel segment is a non-ordinary tunnel segment, obtain the distance measurement of the non-ordinary block.

[0134] When the segment is a non-ordinary segment (such as a K-type segment), since the non-ordinary segment (such as a K-type segment) is smaller than the ordinary segment, only B1 and the vacuum suction port of the non-ordinary segment cavity of the vacuum suction cup participate in the lifting of the segment.

[0135] S702. Based on the non-ordinary block ranging distance and the preset second ranging adjustment strategy, confirm whether to enter vacuum adsorption mode or cleaning mode.

[0136] S703. When entering the cleaning mode, the surface of the tube segment is cleaned according to the preset cleaning strategy.

[0137] Optionally, when the B1 ranging distance is greater than 600mm, the vacuum adsorption mode is entered: the V5 solenoid valve does not operate according to the design, the BC port is connected, the negative pressure chamber is continuously evacuated, and V1, V2, V3, and V4 are de-energized and do not operate according to the design.

[0138] Optionally, when the B1 measuring distance is less than or equal to 600mm, the cleaning mode is entered: V5 is energized and engaged as designed, AB ports are connected, C port is closed, and A port is connected to the atmosphere. Air is drawn into the vacuum pump through AB ports to provide an air source for cleaning and dust removal.

[0139] At this time, V3 and V5 are energized simultaneously, while V2 is de-energized and does not operate. The sucked-in air is then discharged through the vacuum pump exhaust port, through the AB port of V3, through the BC port of V2, and finally discharged through the non-ordinary block cavity vacuum suction port of the tube at the bottom of the suction cup, thereby achieving automatic cleaning of the surface of the tube in Zone II of the suction cup.

[0140] Optionally, when the suction cup continues to descend and the feedback value of the B1 distance measurement is less than 100mm, it enters the vacuum adsorption mode: V3 and V5 are de-energized and reset, the BC port of V5 is connected, and the vacuum pump is connected to the negative pressure chamber; the vacuum pump exhaust is discharged to the atmosphere through the AD port of V3.

[0141] In this embodiment, by dynamically monitoring the ranging distance for non-ordinary segments (such as K-type segments) and using a second ranging adjustment strategy, intelligent switching between vacuum adsorption mode and cleaning mode is achieved. This improves the accuracy of hoisting non-ordinary segments, surface cleanliness, and equipment automation level, avoiding hoisting failures or equipment damage caused by size differences or surface contamination, thereby improving the cleaning efficiency of the segments.
